For decades there has been raging a kind of subterranean debate, one of monumental importance. It is about the Holocaust -- not whether it happened, but HOW it happened, and to what EXTENT. On one hand we have the traditional, orthodox view: six million Jewish victims, gas chambers, cremation ovens and mass graves. On the other hand a small, renegade band of writers and researchers refuse to accept large parts of this story. These revisionists, as they call themselves, present counter-evidence and ask tough questions.
